1 Claim.

This invention relates to a smoking pipe, and has for the primary object the provision of means for improving the smoking qualities of such a device through the elimination of distasteful substances from entering the mouth of the smoker during the use of the device, such substances as tobacco, particles of tobacco, and the like, the device being so constructed that cleaning thereof may be thoroughly and rapidly carried out.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more iulli7 described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a top plan view illustrating a smoking pipe constructed in accordance with my invention with a portion thereof removed.

Figure 2 is a side elevation, partly in section, illustrating the smoking pipe.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Referring in detail to the drawing, the numeral 5 indicates a bowl of a smoking pipe which may be of any desired shape and material and has integral therewith a stem 6 to which is detachably connected a bit l.

The tobacco chamber of the bowl 5 is indicated by the character 8 and the bore of the stem 6 by the character 9. It will be seen that the bore 9 extends the full length of the stem 6 to connect at one end with the bore of the bit 1, while the other end of the bore 9 opens outwardly through an exterior face of the bowl and is normally closed by a removable plug Ii).

It will be seen that the bore 9 of the stem 6 is straight throughout the length of the stem 6 and also in alignment with the bore of the bit so that when the plug IB is removed a pipe cleaner may be readily and conveniently passed through the bores described for the purpose of removing foreign matter therefrom.

The upper edge of the bowl 5 is cut away to form a recess II, the end walls of which are undercut and the lower wall has formed therein a cross channel I2. A closure I3 having beveled end walls to frictionally t the undercut walls of the recess acts to close the cross channel I2 and thereby form in the bowl adjacent its upper end a cross smoke passage and leading therefrom in a downward direction are smoke passages I5 formed in the wall of the bowl and open outwardly into the tobacco chamber 8 adjacent the lower end thereof. Also, communicating with the cross smoke passage and formed in the wall of the bowl is a vertically arranged smoke passage IB, the lower end of which connects with the bore 9 of the stem 6.

Thus it will be seen that when the pipe is smoked, the smoke from the burning tobacco within the chamber 8 must pass upwardly through the passages I5, then through the cross passage, downwardly through the pasasge I6 to the bore Sbefore reaching the bore of the bit and the mouth of the user. Consequently all liquid substances from the tobacco are prevented from entering the bore 9 and commingling with any saliva or juices that may collect in the bore 9. This to a great extent will prevent distasteful substances from reaching the mouth of the smoker. The closure I3 being removable will permit the passages formed in the bowl to be readily cleaned through the use of a pipe cleaner and as before stated, the bore 9 of the stem 6 and bore of the bit l being in direct alignment will permit these bores to be kept in a clean and sanitary condition through the cleaning thereof by a pipe cleaner passed therethrough. Or, if desired, when the plug I0 is removed the user of the pipe may blow through the bore 9 and thereby remove any foreign matter therefrom.

The passages being constructed in the wall of the bowl as specied will, to a great extent, prevent carbon forming in the bowl or chamber thereof as the tobacco will be prevented from becoming saturated with saliva or similar fluid which will permit the entire amount of the tobacco to readily burn within the chamber and thereby relieve what is termed in the art as soggy heels of tobacco in the bowl.

It is believed that a pipe constructed in accordance with the foregoing will not readily become clogged by particles of tobacco and other substances and further it is believed that a pipe of this kind will more readily stay lighted with ordinary attention by the smoker.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

In a smoking pipe, a bowl including inner and outer vertical walls and a bottom wall, a stem on said bowl and having a straight smoke passage extending fromthe end thereof through the bottom wall of said bowl, a plug closing one end of the passage, a bit connecting with said endof the stern and therpassage, said bowl having a recess in the upper edge between the inner and outer 5 vwalls thereof and extending for a. limited distance of the complete circumference of the bowl, said bowl provided with passages connecting with the recess and with the interior of the bowl adjacent the bottom wall thereof, and a passageconnectl0 ing with the passage of the stem and with the recess, said recess being defined by bottom and end walls with the passages of the bowl extend- Ving through the bottom wall thereof, and a plate for closing the recess and coacting therewith to connect the passages of the bowl with each other and having a wedge fit with the end walls of said recess.
